| Applications |
| The MMS is used for automatic monitoring of mercury concentration in rooms like cellrooms of chlorine-alkali plants, laboratories, recycling plants, gas industry, etc. |
|
| Principle of Operation |
| A sample is continously pulled down each line by a powerful sample bypass pump. The sample to be measured is automatically switched to the photometer by a multiplexor valve unit and drawn into the measuring cell by a membrane pump. |
|
| Construction |
| The system consists of the Mercury Vapor Monitor VM-3000, the Multiplexor unit and a PC with MMS-WIN software. The analyzer/multiplexor unit is built in a rugged industrial grade housing (NEMA 4X, IP 65). The data transfer between analyzer and computer can either be through a RS 232 or RS 485 connection or via an fibre optic cable. |
|
| MMS-WIN Software |
| The system includes a software for operational checks, data aquisition, visualisation, interpretation and storage. During operation the software permanently monitors the status of the analyzer and gives alarm on malfunction. Following parameters can be set by the user: duration of measurement and alarm levels for each channel, dead time after switching to the next channel. At any time the system cycle can be interrupted and the analysis be dedicated to a selected sample point. It is also possible to exclude any sample stream from analysis. Daily, weekly, monthly, and yearly reports are printed out and filed automatically (EXCEL format). |
